This is the first winter I have driven my 2002 Explorer which I bought used. It has the electronic climate control, V6, and 42,000 miles. It seems like it takes a disproportionate amount of time for this truck to warm up compared to other cars I have owned and when it does the heat still isn't that hot. I can get confortable but I have the fan and temp all the way up on my 10 mile drive to he train. This is not the case with the Nissan Murano I have had for the last few weeks while the Ford is in the body shop. I live in Illinios so it does get cold here. Last summer I had the radiator flushed and new antifreeze put in. Is this normal operation or could there be something wrong with this truck? If there is something wrong how do I fix it? Any theories would be greatly appreciated! Thank You!
